Update Form1.cs

Added line to update "currentDAWName" on client disposal. Fixes a bug where opening, closing, and opening the same DAW again breaks rich presence functionality until DAWRPC is restarted or different DAW is opened.

You said in the PR that you "fixed a bug where opening, closing, and opening the same DAW again breaks rich presence functionality until DAWRPC is restarted or different DAW is opened", but I couldn't see anything related to that bug in your commits. Did you forget to push any commits or did you have another reason?

Yes, I just added "currentDAWName = DAWName.Text;", that one line was enough to fix the bug.

I believe the bug happened because when previously disposing the client/closing the DAW, "currentDAWName" never got updated to reflect the DAW being closed at any point. So when trying to open a DAW (Ableton in my test) multiple times in a row, I don't think it could triggered line 362 in this file past the first time. Adding this line to update "currentDAWName" upon client disposal allows 362 to trigger every time opening the same DAW repeatedly.
